tClaims. (Cl. 2'23-68) The invention. 'isdisclosed and related more particularly to adjustable "arms fors'manikins for displaying garments.

Among the objects. of the invention is the provision/of. mechanical: joints for the limb: assemblies of manikinsv for displaying garments in a realistic manner simulating human postures.

Another obj ect. isi'the'provision of sturdy'struc-- tures in such limbs. able: to withstand rough handling, accidental falls; and storage accidents to which such marriki'ns are subjected.

Other objects and: advantages will appear as in the specification the description proceeds. and drawings the invention is disclosed in its preferred form. 'But it. is to be understood that it is not. limited to" this 'form; because it may be embodied in modifications within the spirit of the invention asdefined in the claims following the description.

In the one sheet of drawings:

Fig. 1 is a front elevation of the upper portion of a manikin equipped with full length arms articulate'd-in accordance with this invention.

Fig- 2 is anenlarged detail in side elevation from the inner side of a manikin arm partially broken away in vertical section and showing the inner structure of the variousjoints in the arm.

Fig. 3 is a fragmentary detail in front elevation of the elbow portion of the. arm.

Fig". 41s a detail in vertical section of the wrist portion of the. arm.

Fig. fi ls a reduced detail in front elevation of the shoulder plate of the upper arm.

In detail the structure shown in Fig. 1 comprises the shoulder portion A of the manikin body having the flat wooden block I fixed therein. The flat plate 2 is attached to this block by screws and has the stud bolt with the round head 3 mounted in the plate with the interposed friction discs at 4, permitting the bolt to rotate relative to said plate to which it is fixed by the nut 5 threaded thereon. The hemispherical bolt head 3 has the lateral slots 6, l on its sides respectively, in accordance with my copending application Serial No. 772,541, entitled Manikin Joint.

The upper arm B and lower arm C are preferably formed from aluminum or plastic tubing. The upper arm has the circular plate 8 with an ofi-center round hole 9 to pass the head 3 of the bolt with the lateral slot l so placed that the upper arm plate 8 is suspended coaxially with the bolt head 3, from which it may be dismounted by lifting the arm until the bolt head 3 alines with the round hole 9, see Fig. 5.

The plate 8 has the interspaced brackets ll,

2 l2, integral with the plate, preferably in cast aluminum. The tubular bushing l3 extends be tween these lugs. The upper arm 3 has the projecting lugs I4, 15, fixed to the upper end of the upper arm by the screws [6, H, and terminating inlateral al inement with the brackets H [2, to which they are held by the Phillips screw l8, passing through the bushing 13. Friction discs are interposed at I9, I 9, between the brackets ll, I2, and the lugs l4, P5, to retard theoutward swing of the upper'arm B and hold it in adjusted position. The plate 8 has the lateral shields 29, 2|, for concealing the shoulder joint, the latter having the opening 22, giving access to the head of the Phillips screw. The plate 8 also has the semicircular shield 23 extending over the brackets [1,12 and coacting with the shields 2| to give a rounded contour to the shoulder joint of the arm with the shoulder A of the torso of the manikin. The shield 2| has the opening 22, permitting access to the screw [8.

The elbow joint comprises the circular base 21lwith the annular'fi'ange 25 fixed in the lower end of the upper arm B. The square swivel stem 26 extends upwardly through the center opening through the base and engages the square holein the-hub of the rotary head 21, bearing against the upper face of the base 24 to which it" is attached by the nut 2i! on the end of the stem 25 The upper arm has the slot 29 therethrough and giving access tothe nut28, see Fig. 3. The'stem 25 has the circular flange 3!! bearing against the flat face of the base 24' with the friction disc interposed at 3| therebetween and held in frictional relation by the nut 21. This circular flange 30 has the integral circular extension 32 projecting downwardly therefrom, Fig. l.

The tubular forearm C has the opposed lugs 33, 34 fixed in its upper end and attached to the extension by the transverse screw 35 with the friction discs 36, 31 interposed therebetween and held under pressure by the screw 35. This forms in effect a universal and swivel joint capable of pivotal movement in axial and lateral relation to the upper arm B. A particular feature of the forearm is the cut away portion at 38, permitting the forearm to assume an acute angle to the length of the upper arm as indicated in dotted lines Fig. 1.

The hand D is adjustably joined to the forearm by the wrist joint comprising the wooden plug fixed in the lower end of the forearm and having a square axial hole therethrough and provided with the opposed spring detents 4|, 42 fixed in the plug 40, Figs. 1, 4. The hand D has the square wrist pin 43 with lateral notches such as 44 in the sides thereof for engaging the detents 4| and 42. The pin 43 has the flat head 45 fixed thereon and countersunk into the face of the circular base plate 46 fixed to the upper wrist of the hand D, with an interposed friction disc 41 permitting retarded swiveling of the hand D relative to the axis of the forearm C. The end of the pin 43 is provided with the nut 48 and washer 49 for applying pressure to the interposed friction discs for holding the hand in rotated adjustment. The interspaced notches 44 permit adjusting the arm length in accordance with the sleeve length of the garment being displayed. The swivel mounting of the hand D enables the appropriate arrangement of the hands according to the posture of the manikin torso, as in Fig. 1. A variety of hand shapes are supplied as accessories for more realistic posturing such as holdin a hat in lifted position, simulating the tying of a shoe. where hats or shoes are to be accented in window dressing.

Substantially the same structural joints shown in the arms may be adapted to the legs at hip, knee and ankle, as shown at the'shoulder, elbow and wrist respectively, with appropriate changes in size with the same mode of operation.

This arm structure is ofiered as a combinative unit, because only by the inclusion of the present substantially universal joints at the shoulder and elbow portions and the swivel mounting of the hand, may all the possible postures of the human arm be simulated.

Having thus described this invention and its mode of operation, what I claim and desire to secure by Letters Patent is:

1. A display manikin having an articulated arm structure of readily detachable units capable of retaining any adjusted position comprising a body member having a shoulder plate secured therein, a bolt having its head and slotted shank projecting outwardly from said plate and mounted therein for frictionally retarded rotation, an arm composed of three separable members including an upper arm member, a lower arm member and a hand member, an upper arm plate member having an off-center hole and slot adapted to removably pass the head of said bolt and receive said slotted shank for unitary juncture and rotation, and provided with upper and lateral shields to provide a continuous, natural shoulder contour and prevent drapery from catching in the upper arm joint, and means integral with said upper arm plate and concealed by said shields for securing said upper arm member with frictionally retarded rotary movement in a plane transverse to the plane of said upper arm plate.

2. A display manikin having an articulated arm structure of readily detachable units capable of retaining any adjusted position comprising a body member having a shoulder plate secured therein, a bolt having its'head and slotted shank projecting outwardly from said plate and mounted therein for frictionally retarded rotation, an arm composed of three separable members including an upper arm member, a lower arm member and a hand member, an upper arm plate member having an off-center hole and slot adapted to removably pass the head of said bolt and receive said slotted shank for unitary juncture and rotation, and provided with upper and lateral shields to provide a continuous, natural shoulder contour and prevent drapery from catching in the upper arm' joint, and means integral with said upper arm plate and concealed by said shields for securing said upper arm member with frictionally retarded rotary movement in a plane transverse to the plane of said upper arm plate, said lower arm member having a joint at its upper end with a stem adapted for rotatable engagement with the lower end of said upper arm member and a separate pivotal movement transverse thereto, said hand member having a pin allowing rotation but adapted for quick disengagement with the lower end of said lower arm member, all of the movements of said lower arm and hand members beingfrictionally retarded.
